They're Back! Everyone's favorite aardvark returns to celebrate a quarter-century of success in Arthur's Nose: 25th Anniversary Limited Edition by Marc Brown. As a prologue to this first story in which Arthur starred, Brown shows the evolution of his drawings of Arthur from 1976 to the present, along with a sidebar of ""Fun Facts"" (e.g., ""D.W. has an imaginary friend named Nadine""), followed by a photo gallery of Brown's family with some pretty clear correlations between the author's relatives and Arthur's. Aspiring writers and artists also get a peek at the original manuscript and sketches for Arthur's Nose. (Little, Brown, $15.95 40p ages 4-8 ISBN 0-316-11884-2; Apr.) For story hour, Little House in the Big Woods: Special Read-Aloud Edition by Laura Ingalls Wilder, illus. by Garth Williams, expands its trim size (to 8 U x 10 7/8"") and type size but retains the classic charcoal drawings and the famous tale of Laura and her pioneer family living in the Big Woods of Wisconsin.
